vb6 Runtime: (you need an account to see links)
*make sure to run these as administrator if possible*
64-bit users may also have to install to the SysWOW64 folder (some people I know had to, others haven't)
Some programs may also come with extra files like prjChameleon.ocx, gzip.dll, etc. To use these, you need to copy them to your system32 folder (64-bit may also need it in SysWOW64, see above). If you're still having problems with these files, you need to register them; open up a command prompt (AS ADMINISTRATOR!!) and run this for each file:
So, for example, prjChameleon.ocx would be registered as:
